Title: Bag for preserving platelet and composite bag using the same
Inventor: HAGIWARA SAKIKO
IPC: A61J1/05
Filed: 1990-05-17
Abstract: PURPOSE:To preserve platelet safely for a long time and supply to a human body when required, by mixing specific wt.% citric acid ester with specific wt.% polyvinylchloride. CONSTITUTION:A platelet preserving bag consists of a compound obtained by mixing 20-80 pts.wt. citric acid ester with 100 pts.wt. polyvinyl chloride. Besides them, as material to bag, stabilizing agent, such as calcium or zinc, gliding agent, such as steric acid epoxidated soya bean oil, etc., may be added, if required. Formation of the bag is performed in such steps as mixing a plasticizer with polyvinyl chloride uniformly using a blender or mixer, melting the resultant mixture, intruding into a die in the form of medical bag, followed by blow shaping or extrusion into sheet form, and thereafter heat sealing the end part. Thus, a medical bag is yielded. The thickness of the sheet may be any selected depending upon the intended use, example being 200-500mum.

Title: Method for manufacturing outer blade of electric shaver made of amorphous metal
Inventor: NAWA MASAHIRO
IPC: B21D22/02
Filed: 1980-09-13
Abstract: PURPOSE: To manufacture titled outer blades which are excellent in strength, by transferring a cavity to coining materials for forming outer blade by pressing the coining material against the bottom mold by using a coined plate on which the cavity is transferred, as the top mold.  
     CONSTITUTION: A coining plate 2 made of a soft metal is pressed against a bottom mold C through a coining material 1' for transferring cavity made of an amorphous metal, and the shape of a cavity 3 installed in the bottom mold C is transferred to the coining plate 2. After the shape of cavity 3 is transferred, the coining plate (coined plate) 2 is subjected to an aging treatment as occasion demands and the plate 2 is hardened. Then, a coining material for forming outer blade 1 made of the amorphous metal is pressed against the bottom mold C by using the hardened coined plate 2 as the top mold B, and the shape of the cavity 3 is transferred to the material 1. After the coining is made, holes are made through the material 1 by grinding and thus outer blades of electric shavers are manufactured. When this process is applied, contractions of cross-sectional area at the shoulder section of the cavity 3 can be prevented, and, therefore, outer blades which are excellent in strength can be formed.

IPC: F28D1/04
Filed: 1994-06-09
Abstract: PURPOSE:To prevent frost from being deposited on coils of a heat exchanger without degrading the effect of heat exchange while using a counter-flow type heater exchanger which is easy to manufacture and maintain. CONSTITUTION:Heat exchangers 1 and 2 consisting of counter-flow type fins are vertically stacked by a number of stages where each counter-flow fine is connected to each other in series, thereby leading an inside fluid to upper stage coils from lower stage coils one by another so that the air may pass horizontally between the counter-flow type fins, which results in a differential temperature on an air intake side in each stage of the heat exchanger. This construction makes it possible to prevent frost from being deposited on the whole surfaces of the tubes at the same time.

Abstract: PROBLEM TO BE SOLVED: To provide a compact and inexpensive wind vane and anemometer without mechanically movable parts by providing a thermal anemometer part for measuring a wind speed and a thermal anemometer part for determining a wind direction including a shielding body. SOLUTION: A thermal anemometer part 1 for measuring a wind speed comprises a sensor 3 attached to a tip of a column 2 with a lead 4 of the sensor 3 extracted. A thermal anemometer part 5 for determining a wind direction comprises a sensor 7 attached to a tip of a column 6 with a lead 8 of the sensor 7 extracted outward. The sensor 3 receives a wind from all directions and measures the wind speed. On the other hand, the sensor 7 is shielded from a backwind by a conic shield 10 for receiving approximately only a forewind and measures its wind speed. In this case, measurement results D1 , D2 of both anemometer parts 1, 5 are approximately equal to each other in the case of the forewind, while the measurement result D2 of the anemometer part 5 is remarkably small in the case of the backwind, so that a difference between the results D1 , D2 is large.  Based on the determination result and the wind speed, measurement of a wind direction and a wind speed is done.

CONSTITUTION:A guide rod is fixed to an arrangement formed as a combination of a ring- shaped permanent magnet 4 consisting of rare earth with an electric magnet 5 having the same core dia. as the outside dia. of the permanent magnet 4, and a table 2 on which another permanent magnet 3 of the same type as this stationary permanent magnet 4 is arranged so that poles in the same polarity face each other, and put afloat by the repulsive force of the magnetic poles generated in between. The displacement of the table oversurface is sensed by a contactless displacement meter 1 and passed through a DC component canceling adapter 7, and thus the output voltage in the balancing point is nullified. This output voltage is diverged, and one of them is passed through a differentiation circuit 8 to be converted into a speed voltage, which is fed to the speed terminal of an addition circuit 9. The addition circuit 9 adds together the displacement voltage and speed voltage in a proportion equal to their optimum feedback coefficients, and the output voltage is amplified by a power amplifier 10 to acquire necessary operating current.
